Abstract
Description
Technical Field
[0001] The present invention relates to the field of communications, and particularly to a wiring device and equipment. Background Art
[0002] A terminal is a commonly used component for connecting electrical circuits, mainly playing the role of electrical connection and signal transmission between devices and components, components and cabinets, and systems and subsystems. Moreover, the terminal can maintain the system-to-system signal distortion and energy loss unchanged, so the terminal is widely used in the connection and transmission of long-distance signals.
[0003] Generally, two terminals are not electrically connected to each other. Therefore, when in use, if two terminals need to be connected, an external wire is required for electrical connection. For example, in the project of the air suspension series frequency conversion cabinet, terminals are required to transmit the signals between the frequency conversion cabinet and the external control box. Wires are used to connect the terminals on the frequency conversion cabinet and the terminals on the external control box to realize the control signal docking between the frequency conversion cabinet and the external control box. In practical applications, the frequency conversion cabinet is only wired to the external control box during the whole machine test, but it does not need to be wired to the external control box during other tests and debugging. Therefore, the terminals on the frequency conversion cabinet connected to the external control box do not need to be connected with wires. However, at this time, the main board in the frequency conversion cabinet will misread the emergency stop signal, resulting in the frequency conversion cabinet reporting protection as soon as it is powered on and the circuit breaker tripping. Therefore, the frequency conversion cabinet cannot be powered on and run normally. In the prior art, to solve this problem, the terminals on the frequency conversion cabinet connected to the external control box are directly connected with wires, so that the main board will not misread the emergency stop signal when the frequency conversion cabinet is powered on. However, the method of using external inserted wires for connection will make the wire connection in the whole experiment process more complex, so it is easy to make wiring errors during the wiring process, and it is not convenient to troubleshoot faults once a wiring failure occurs. Summary of the Invention
[0004] In order to solve the technical problem that the method of using an external wire to connect two non-conductive terminals in the above prior art is prone to errors, the present invention proposes a wiring device and equipment.
[0005] The technical solution adopted by the present invention is as follows:
[0006] The present invention proposes a wiring device and equipment, wherein the wiring device includes: at least two terminals, each terminal is provided with a plurality of wiring holes internally provided with conductive members, all the conductive members on each terminal are connected in series and conduct electricity, and further includes a connecting member for electrically connecting two of the conductive members, the two conductive members connected by the connecting member are respectively located on two terminals, and when a wire is inserted into the wiring hole, the conductive member is separated from the connecting member.
[0007] Further, the conductive member includes a contact portion and a butting portion. The butting portion abuts against the housing of the terminal block, and the contact portion is located below the wiring hole. The wire inserted into the wiring hole is in electrical contact with the contact portion and separates the butting portion from the housing.
[0008] Further, the connecting member is fixed to the housing, and the connecting member is clamped between the housing and the butting portion.
[0009] In one embodiment, the conductive member is an a-shaped elastic piece. The circular portion of the a-shaped elastic piece includes the butting portion, and the tail portion of the a-shaped elastic piece includes the contact portion.
[0010] Further, a conductor for serially conducting all the conductive members is provided in the housing. The conductor is located below the conductive member and is in contact with the conductive member.
[0011] Further, a plurality of jacks are provided on the housing. The jacks are located above the butting portion. A tool is inserted into the jacks to separate the butting portion from the housing.
[0012] In one embodiment, two terminal blocks are included. Each terminal block includes two wiring holes arranged at intervals and a communication groove communicating the two wiring holes. A conductor for serially conducting the conductive members inside the two wiring holes is placed in the communication groove.
[0013] In one embodiment, two connecting members are further included. One connecting member connects two conductive members, and the other connecting member connects another two conductive members.
[0014] An apparatus using the wiring device described above.
[0015] Further, the apparatus includes a frequency conversion cabinet.
[0016] Compared with the prior art, the wiring device proposed by the present invention realizes electrical connection between two non-conductive terminal blocks without external insertion of wires by setting a connecting member. And when wires are externally inserted into the corresponding wiring holes, the connecting member will disconnect the connection with the two terminal blocks, thus not affecting the use of externally inserted wires on the terminal blocks. Therefore, the wiring device proposed by the present invention can not only simplify the connection method, but also provide multiple usage modes for users. Description of the Drawings

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0026] The wiring terminal is a commonly used component for connecting electrical circuits, mainly playing the role of electrical connection and signal transmission between devices and components, components and cabinets, and systems and subsystems. And the wiring terminal can keep the signal distortion and energy loss changes from occurring between systems. Therefore, the wiring terminal is widely used in the transmission of long-distance signals.
[0027] Generally, the two terminal blocks are not electrically connected to each other. Therefore, when in use, if it is necessary to connect two terminal blocks, an external wire needs to be used for electrical connection. For example, in the air suspension series frequency conversion cabinet project, terminal blocks are required to transmit signals between the frequency conversion cabinet and the external control box. Wires are used to connect the terminal blocks on the frequency conversion cabinet and the terminal blocks on the external control box to achieve the docking of control signals between the frequency conversion cabinet and the external control box. In actual applications, the frequency conversion cabinet is only connected to the external control box during the whole machine test, but it is not necessary to connect to the external control box during other tests and debugging. Therefore, there is no need to connect wires to the terminal blocks on the frequency conversion cabinet for connecting to the external control box. However, at this time, the main board in the frequency conversion cabinet will misread the emergency stop signal, resulting in the frequency conversion cabinet reporting protection as soon as it is powered on and the circuit breaker tripping, so the frequency conversion cabinet cannot be powered on and operated normally. In the prior art, to solve this problem, the terminal blocks on the frequency conversion cabinet for connecting to the external control box are directly connected by wires, so that the main board will not misread the emergency stop signal when the frequency conversion cabinet is powered on. However, the method of using externally inserted wires for connection will make the wire connection in the whole experimental process more complicated, and the wire connection needs to be changed according to different test items during the test. Therefore, wiring faults are likely to occur during the wiring process and the debugging process, and it is not convenient to troubleshoot the faults once they occur.
[0028] Therefore, in order to solve the technical problem that the method of using externally inserted wires to connect two non-conductive terminal blocks in the prior art is prone to errors, the present invention proposes a wiring device, comprising:
[0029] At least two terminal blocks, each terminal block is provided with a plurality of wiring holes internally provided with conductive members, and all the conductive members on each terminal block are connected in series. If only one terminal block is needed to connect two electrical appliances, only need to use a wire to connect a wiring hole on this terminal block and one electrical appliance and then use another wire to connect another wiring hole on this terminal block and another electrical appliance.
[0030] In particular, it further includes a connecting member for electrically connecting two conductive members. The two conductive members connected by this connecting member are respectively located on two terminal blocks. Therefore, the electrical connection between two non-conductive terminal blocks is achieved without using the method of externally inserted wires. And when a wire is inserted into the wiring hole corresponding to the conductive member connected by the connecting member, the connecting member will be separated from this conductive member. The connecting member will neither affect the use of externally inserted wires of the terminal block nor prevent the electrical connection of two non-conductive terminal blocks without externally inserted wires.
[0031] In summary, the wiring device proposed by the present invention realizes electrical connection between two non-conducting wiring terminals without externally inserting a wire by setting a connecting member, and the connecting member will disconnect the connection with the two wiring terminals when a wire is externally inserted into the corresponding wiring hole, thus not affecting the use of the externally inserted wire on the wiring terminal. Therefore, the wiring device proposed by the present invention can not only simplify the connection method but also provide multiple usage methods for users.
[0032] Furthermore, the conductive member includes a top contact portion and a contact portion. When no wire is inserted into the wiring hole corresponding to the conductive member, the top contact portion is in top contact with the housing of the wiring terminal, and the contact portion is located below the wiring hole corresponding to the conductive member. When a wire is inserted into the wiring hole corresponding to the conductive member, the contact portion is in electrical contact with the wire and at the same time the top contact portion is separated from the housing.
[0033] Furthermore, both ends of the connecting member are respectively fixed on the housings of the two wiring terminals, and the end portion of the connecting member is clamped between the housing and the top contact portion of the conductive member. When no wire is inserted into the wiring hole corresponding to the conductive member connected by the connecting member, since the top contact portion of the conductive member is in top contact with the housing, the connecting member is in electrical contact with the top contact portion of the conductive member, so the connecting member realizes the electrical connection between the conductive members on the two wiring terminals, thus realizing the electrical connection between the two wiring terminals. When a wire is inserted into the wiring hole corresponding to the conductive member connected by the connecting member, at this time the top contact portion of the conductive member is separated from the housing, so the connecting member is also not in contact with the top contact portion of the conductive member, so the connecting wire disconnects the electrical connection between the two wiring terminals.
[0034] The principle and structure of the present invention will be described in detail below in conjunction with the drawings and embodiments.
[0035] First, Figure 1 and Figure 5 will be used to introduce the wiring device in the prior art. Specifically, as Figure 1 shown, the wiring device includes two wiring terminals - the first wiring terminal 1 and the second wiring terminal 2. Each wiring terminal is provided with two series-connected and conducting wiring holes. The two wiring terminals are arranged closely in two rows. The two wiring terminals cannot achieve electrical connection without externally inserting a wire. Among them, the first wiring terminal 1 includes a first wiring hole 11 and a second wiring hole 12, the second wiring terminal 2 includes a third wiring hole 21 and a fourth wiring hole 22. The first wiring hole 11 and the third wiring hole 21 are on a straight line, the second wiring hole 12 and the fourth wiring hole 22 are on another straight line, and the first wiring hole 11, the second wiring hole 12, the third wiring hole 21 and the fourth wiring hole 22 enclose a square. For example, as Figure 5As shown in the figure, the wiring device is specifically used in the overall debugging process of the frequency conversion cabinet and the external control box or the individual debugging process of the frequency conversion cabinet. The frequency conversion cabinet 3 is provided with a main board, a 24V power supply and a wiring device. Among them, the main board and the first wiring hole 11 are connected by an externally inserted wire, and the 24V power supply and the third wiring hole 21 are connected by an externally inserted wire. A first emergency stop button 5 is provided between the main board and the first wiring hole 11. The first emergency stop button 5 is closed under normal conditions. Once the first emergency stop button 5 is pressed, it will be in an open state. Similarly, the external control box 4 is provided with two unconnected fifth wiring holes 41 and sixth wiring holes 42. A second emergency stop button 9 is also provided between the fifth wiring hole 41 and the sixth wiring hole 42. The second emergency stop button 9 is closed under normal conditions. Once the second emergency stop button 9 is pressed, it will be in an open state. When the frequency conversion cabinet 3 and the external control box 4 are debugged as a whole, it is only necessary to connect the fifth wiring hole 41 to the second wiring hole 12 through an externally inserted wire and connect the sixth wiring hole 42 to the fourth wiring hole 22 through an externally inserted wire, so that an electrical connection is achieved between the frequency conversion cabinet 3 and the external control box 4. During the debugging process, if the main board reads a high-level signal, it indicates that the first emergency stop button 5 and the second emergency stop button 9 are both closed at this time, the circuit breaker does not trip, and the frequency conversion cabinet 3 is working normally; if the main board reads a low level during the debugging process, it indicates that the first emergency stop button 5 and / or the second emergency stop button 9 is in an open state at this time, then the circuit breaker trips and the frequency conversion cabinet 3 stops running. When the frequency conversion cabinet 3 is debugged individually, there is no wire connection between the fifth wiring hole 41 and the third wiring hole 21, and there is no wire connection between the sixth wiring hole 42 and the fourth wiring hole 22. At this time, the first wiring terminal 1 and the second wiring terminal 2 are not conducting, so the main board will read a low level at this time, and the circuit breaker will trip and the frequency conversion cabinet will stop running. Therefore, the frequency conversion cabinet will always report an error during debugging. To solve this problem, in the prior art, it is necessary to externally insert a wire to connect the second wiring hole 12 and the fourth wiring hole 22 so that the main board can normally read a high level and the frequency conversion cabinet can run normally for debugging. However, the debugging is software debugging, but not all software debugging personnel understand the electrical circuit principle. Therefore, during the actual debugging process, there have been cases where software debugging personnel, due to not understanding the internal structure of the wiring terminal and the circuit principle, caused the frequency conversion cabinet to always report an error during the individual debugging process and could not be debugged normally.
[0036] Therefore, in view of this problem, the present invention has been modified on the basis of the existing wiring device to avoid this situation from happening again. As Figure 2As shown in the figure, the present invention uses a connecting member 7 to pass through the housings of the first terminal 1 and the second terminal 2, so as to electrically connect the first wiring hole 11 and the third wiring hole 21 internally, and electrically connect the second wiring hole 12 and the fourth wiring hole 22. Further, the connecting member can only achieve the electrical connection between the first wiring hole 11 and the third wiring hole 21 when no wire is inserted into them, and the electrical connection between them will be disconnected when a wire is inserted into the first wiring hole 11 and / or the third wiring hole 21.
[0037] Specifically, as Figure 3 and Figure 4 shown, the housing of the first terminal 1 is provided with a first wiring hole 11 and a second wiring hole 12 at intervals. The bottoms of the first wiring hole 11 and the second wiring hole 12 are provided with a communication groove, and the communication groove communicates the first wiring hole 11 and the second wiring hole 12. A conductive member 6 is provided in each of the first wiring hole 11 and the second wiring hole 12, and a whole conductor is placed in the communication groove, the first wiring hole 11 and the second wiring hole 12, and the conductor fits against the inner wall of the housing. Specifically, the first wiring hole 11 and the second wiring hole 12 include a cylindrical portion for inserting a wire and an irregular groove portion for placing the conductive member. The conductive member 6 is a spring piece in the shape of an "a". When the "a"-shaped conductive member 6 is placed in the first wiring hole 11 and the second wiring hole 12, its circular portion will be closely fitted and pressed against the conductor and the inner wall of the housing, so as to be fixed in the first wiring hole 11 and the second wiring hole 12, and the two conductive members are connected in series through the conductor. The part of the "a"-shaped conductive member 6 that is pressed against the housing is the abutting portion 61. The tail part of the "a"-shaped conductive member 6 is located directly below the cylindrical portion of the first wiring hole 11 and the second wiring hole 12 for inserting the wire. When a wire is inserted into the first wiring hole 11 and the second wiring hole 12, the tail part of the "a"-shaped conductive member 6 will be in electrical contact with the wire, and the part of the "a"-shaped conductive member 6 that contacts the wire is the contact portion 62. At the same time, the tail part of the "a"-shaped conductive member 6 will be deformed downward under force, so that the abutting portion 61 will be separated from the inner wall of the housing under force.
[0038] Similarly, the structure of the second terminal 2 is the same as that of the first terminal 1.
[0039] Furthermore, the connecting member passes through the housings of the first terminal 1 and the second terminal 2 to connect the conductive members 6 in the first wiring hole 11 and the third wiring hole 21, thereby realizing electrical conduction between the first wiring hole 11 and the second wiring hole 12, and further realizing the electrical connection between the first terminal 1 and the second terminal 2. Specifically, the connecting member 7 is a conductor. One end of the connecting member 7 is fixed on the inner wall of the housing of the first terminal 1, and this end portion is clamped between the abutting portion 61 and the housing. The other end of the connecting member 7 is fixed on the inner wall of the housing of the second terminal 2. Similarly, this end portion is also clamped between the abutting portion 61 and the housing. From the specific structures inside the first terminal 1 and the second terminal 2 and the positional relationship of the connecting member 7, when no wire is inserted into the first wiring hole 11 and the third wiring hole 21, at this time, the abutting portion 61 of the conductive member 6 in the first wiring hole 11 and the third wiring hole 21 is in pressing contact with the housing. Since the connecting member 7 is clamped between the abutting portion 61 and the housing, at this time, both ends of the connecting member 7 are in contact with the conductive members 6 in the first wiring hole 11 and the third wiring hole 21 respectively. Therefore, electrical conduction is achieved between the first wiring hole 11 and the third wiring hole 21. When a wire is inserted into the first wiring hole 11 and / or the third wiring hole 21, the abutting portion 61 of the conductive member 6 in the first wiring hole 11 and / or the third wiring hole 21 will be separated from the housing due to the force. Then, the connecting member will also be separated from the conductive member 6 in the first wiring hole 11 and / or the third wiring hole 21. Thus, electrical conduction between the first wiring hole 11 and the third wiring hole 21 no longer exists.
[0040] Similarly, electrical conduction between the second wiring hole 12 and the fourth wiring hole 22 is also achieved through the connecting member 7.
[0041] Therefore, as Figure 5 and Figure 6As shown, when the wiring device proposed by the present invention is used in the overall commissioning process of the frequency conversion cabinet and the external control box or in the individual commissioning process of the frequency conversion cabinet, the problems existing in the prior art will not occur. When the wiring device is used in the overall commissioning process of the frequency conversion cabinet and the external control box, the connection modes of the first wiring hole 11, the second wiring hole 12, the third wiring hole 21 and the fourth wiring hole 22 remain unchanged. At this time, since wires are inserted into the first wiring hole 11, the second wiring hole 12, the third wiring hole 21 and the fourth wiring hole 22, the connector 7 and the conductive part 6 are separated at this time. Therefore, the internal connection situation of the entire wiring device is the same as that in the prior art, and no modification is required during the entire commissioning process. When the wiring device is used in the individual commissioning process of the frequency conversion cabinet, after the wires on the second wiring hole 12 and the fourth wiring hole 22 are pulled out, the connector 7 will electrically connect the second wiring hole 12 and the fourth wiring hole 22. Since wires are externally inserted into the first wiring hole 11 and the third wiring hole 21, the connector 7 will not electrically connect the two. Therefore, at this time, the frequency conversion cabinet can operate normally without using an externally inserted wire to connect the fourth wiring hole 22 and the second wiring hole 12. The software debugger can directly perform the individual commissioning of the frequency conversion cabinet after pulling out the wire, which greatly simplifies the commissioning process and reduces the possibility of commissioning failures.
[0042] Furthermore, a jack is also provided on the housing of the terminal block. The jack is located directly above the abutting part of the conductive part. When a wire is inserted into the wiring hole, a tool can be inserted into the jack to assist in separating the abutting part from the housing.
[0043] In this embodiment, the number of terminal blocks included in the wiring device is not limited, and the number of wiring holes on each terminal block is also not limited. In addition, the specific shape of the conductive part is not limited.
[0044] In summary, the wiring device proposed by the present invention greatly simplifies the connection between electrical appliances and reduces the possibility of connection failures. Moreover, the wiring device proposed by the present invention can be used flexibly. It can be used normally when wires are externally inserted into the wiring holes, and it can also electrically connect two wiring holes without externally inserting wires.
[0045] The present invention also proposes a device that uses the wiring device described above. The wiring device includes a frequency conversion cabinet.
